' Be itJ-know'n tha I, WILLIAM A. CAREY, a citizen of the United States, and 'a resident of Toledo, in the county ofvLu'cas and State of Ohio, have made an'Invention Appertaining to'a Mold for Plastic Flower Boxes or the like; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others "skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the "characters of reference marked thereon, which form apart of this specification,

This invention relates to molds for plastic.

material and particularly to a mold'for making flower boxes and the like; n The object of the invention' s the provision of a simple and inexpensive knock-down mold" of the character .described,"wh1ch is strong and rigid in its construct1on,'ch angeable as to 'size and capable of being-easily and-quickly knocked down or built up, and

"of being changed'to suit'the si' e"'or' end designs desiredon the molded article,

The invention is fully described "the following specification, and while, iits broader aspect it is-capable 0f embod1ment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which I Fig; 1' is a perspective 'view .of a "mold embodying the mventionwith parts broken 1 away. Fig. 2'is an end view thereof withia part'broken away. Fig. 2" is a reduced bottom view. Fig. 3 is a fragmentaryfsection 011 the line 33 in Fig 2. Fig.4 is an enlarged bottom view of a corner portion of I the mold, and Fig 5 is a perspective fragmentary view of twofdesign strips and a corner" fillet member in assembled relation.-

Referring to the drawings, 1 designates the bottom, 2,2 the opposing sides and 3,; 3 the opposing ends of the mold, the side and ends preferably having miteredcorner joints; 7 secured together at their corners adjacent to the upper and'low'er edges thereof by'rele'as able fastening means 4 of any suitable form,

which in the present-instance comprises an' also adapt the bars to lifting theimold.

The; sides and ends are releasably ion by a set of fastening means angled" strap member hinged to theas a tive ends and adapted to extend around the The sta le and strap members ma be sesides with one'o'r more dovetail pojrtionsj-7 wh ch fit Into dove -tail grooves 8 provided-at the inner 'sidesof side-bars 9 longitudinally thereof and-preferably throughout their entir'e 'leng'th; ,The bars 9; 'are'of greater length than the sides 2 and-are intended to have the grooves 8 receive dove-tails-1O provided' on the ends of the respective end members 3' so that theside'bars are interlocked with the endsand cooperatetherewith to prevent any "outward movements'of theside's2; Whileit 'is" preferable to: provide I the sides 2 with projections 7- for I interengagement with ;th e

; side bars 9', they may be entirely eliminated if desired inasmuch as the dove-'ta'ilst lOfof- -theend'membersserve to retainvthe side bars "whichis provided with design stri s capable in'en'gagement with the sides. The side jloar's '9 are made-longer thanthe sides'fltoenable corners and provided near its -'freejend 'with' aneye for receivlng a staple 5 onthe s'ide. I

the mold to be-varied in length bygsubstituting sides of rdifi'er entilength. for those in use,

the ends of'thei mold remaining thesame and ;'being moved inward or ,outwardvalongzthe side bars to suit the lengths of-the sidesemso serve as handles for ployed.-: The projecting ends of the sidebars In order to form the fiower box or other article being molded nearits top ed'ge with a surrounding head, the sides and endsnof the mold are'internally provided: near. .-their top' edges with grooves 11' whichwmeet at their ends to formacontinuous recess around the in nersurface of thevmold adjacent to its upper edge; Itis preferable .toii-longitudi nallyf'ofe'the groovesl'lin'reg-ister with the bottoms thereof, as shown at.12, to form the sides and ends with the uppen'edge'portions 13, which are connected to the" body portions them to be turned outward towfacilitatexthe removal'of the molded article'fromthe mold.

'90 nally split-the endandsidewalls' longitudiof the sides and ends by' hinges 14= to adapt? Each side 2 and end 3 of the mold is provided in its side lengthwise thereof with a recess 15, which is preferably of dove-tail form and in whicha respective design strip 16 of dove-tail or other complemental shape is slidingly mounted, such strips being eoextensive in length with the parts by which carried and having their adjacent ends mitered and in close fitting abutment. It is evident that to change the design formed on the sides and ends of a box being molded it is only necessary to remove one set of design strips and substitute another set therefor. 17 designate fillet strips which are set in the corners of the mold.

- Thetop edges of thesid'es 2 and ends 3, or of the edge portions 13 thereof, if such edge portions are provided, are recessed, as at 18,

to form seats forthe edges of a cover 19, which fixedly carries a core member 20 of box form, the present instance, at its inn r Siidcf core is spaced at its sides, ends and bottom from the respective sides,

;vided with a set of handles 22 to facilitate a removal ofthc coverand its core member 20 from themold box and the cover is also provided withcross-cleats 23 to adapt the mold box, when inverted for filling, to rest on such cleats. The mold box is intended to have the concrete or other plastic material introdnced therein through pouring openings 24 provided in the bottom thereof, in the pres- 1 ant instance at the corners and near [the cen- The bottom 1, which during the pourtier. ing of the concrete or other plastic material into the mold and during the drying operation-fie really the top of the mold, fits loosely into the bottom edge of the mold flush therewith duezto portions ofthe'mold 'sidesand ends fitting into the filling openings 24.

'' tion-the sides 2, endss3 and side bars 9 are top seating in the recess 18 around the top edge of the mold box and the mold is then inverted so that the cleats '23 of the top 19 reston a floor or'other support. This having been done, the bottom 1 is placed in position on the mold bottom and the plastic material may'then bepoured into the mold through the openings 24:. When the molded article has dried sufliciently to permit it to be removed from the mold, the mold is inverted to place its top uppermost and to permit the top 19 and core box 20 to be removed therefrom. The upper edge portions 13 of the sides and ends'arethen turned back to" release the beads formed'on the molded art'icle by the recess 11, and the ends 3 are disconnected from the sides and slid outward therefrom and from engagement with the side bars 9, thus permitting the sides to be moved outward from engagement with the sides of the molded article.

It is evident that if it is desired toincrease the length of the moldedfbox, sides 2 of greater length than those before used maybe employed without changing the endsfthe side bars 9 being freely movable fromejngagem'ent with one set of sides and engaged with tl'lQ'OthQI set. It it also evident that the design strips 16 may be changed at will to suit the design desired, i a

I w'sh it understood vthat my inventionis not limited to any specific construction,.larrangement or form of the parts, as it ifs capable of embodiment in numerous forms without departing from the spirit of the claims. 7 Having thus describedmy invention, what I claim as new and desire to securfeby Letters-Patentia g a 1, A mold-ef the class described having separable side and end members, a sidebar disposed at theouter side of each seamenvber longitudinally thereof, theend membcits and, side bars having releasable dove ran connection which zpermit movements ofthe end members longitudinally of the sidebars and cause the side bars and ehd membersto cooperate to firmly hold the side members against outward movements .2. 1A mold of the class described having side members and end members, the, end members having dove-tail, projections at, their ends, side barsdetachably carriedjby the side members longitudinally and at the outer sides thereof and havingdove tail grooves-at their inner sides for slidingly receiving and interlocking with the respective dove tailprojeetions of the end members.
